Y., ASSIGNOR '10DYEING PROCESSES CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEWYORK ART or TREATING YARN Application filed March 11, 1927. Serial No.174,597.

The present invention relates to the art of treating yarn and similartextile materials with dyeing or other treating fluids while in the formof a cop, bobbin, spool, cheese or 6 other form of package, and itrelates more especially to the preparation of the package preliminarilyto the dyeing or other treatment whereby uniformity in density of theyarn in a plurality of packages will be obtained, thereby insuring evenand thorough dyeing or other treatment of all the yarn in all of thepackages.

According to the present invention, each yarn package is wound on apervious holder which preferably is incompressible axially,

but has a yarn supporting surface'of relatively small area in contactwith the yarn at the center of the package; each yarn pack agecontaining its holder is placed between a pair of heads which areadapted to bear endwise against the ends of the respective package butare capable of'movement axially of the ends of the respective holder;and a suitable number 0 the packages are assembled end to end with theirholders in alinement and abutting endwise and their compression headsarranged to act in pairs on the respective packages interposed betweenthem, and axial compression is applied to the end heads and maintainedthereon. The endwise compression thus exerted on the series or setofpackages is transmitted uniformly to all the packages of the series, aseach package is capable of moving longitudinally on or accommodatingitself to its holder under such compression while the compression headsare unrestrained by the holders, and, hence, the endwise compressionapplied to the outermost heads will be equalized among the variouspackages of the series, 1nsuring equal axial compression of each packageand thus producing the requisite amount of compression of the yarncomposing each.

package to produce uniform permeability thereof, and, in consequence,even dyeing or other treatment of the yarn by the dyeing or othertreating fluid forced through it from its center outwardly, or viceversa, may be attained during the subsequent dyeing or other treatment.

By arranging each yarn package of the series between a pair ofcooperative compres sion heads which are capable of movementindependently of the yarn holders, the several yarn packages of theseries will be properly compressed without requiring the use of a seriesof intermediate trays, which, as heretofore used, have been heavy andinvolved slow and diflicult handling.

1 To these and other ends, the invention consists in certainimprovements and combinations and arrangements of parts, all as will behereinafter more fully described, the features of novelty being pointedout particularly in the claims at the end of the specification.

In the accompanying drawing Figure 1 represents a longitudinal sectionalview of a series ofyarn packages assembled and compressed in accordancewith the preferred embodiment of the present invention;

Figure 2 is a detail sectional view of one of the compression headsemployed in the arrangement shown in Fig. 1;

Figure 3 represents, on an enlarged scale, a top plan or end view of theassembly shown in Figure 1;

Figure 4 is a view of a part of the structure showing means which may beused in some pression of yarn or similar textile materials to secureuniform permeability thereof to liquids, gases or other treating fluids,al-

though the invention is particularly adapted I for the preparation ofyarn packages in the form of cops, bobbins, spools, cheeses and textilefilm in the form of roving tops etc. or the like for dyeing while insuch form by forc lng dyeing liquor through'the package while the sameiscompressed in a manner which will insure uniform density of thepackages,

and, in consequence, even and uniform dyeing. The'preferred embodimentof'the invention will be hereinafter described in detail in connectionwith the accompanying drawing, but it will be understood otherequivalent embodiments of the invention are contemplated, and such willbe included within the scope of the claims.

In the present instance, A represents yard packages which may be ofsubstantially cylindrical or other form and consist of yarn or othertextile thread or textile materials on tops roving etc. each of which iswound upon a pervious holder l'by which is meant a holder which permitsflow of treating fluid radially through the holder from its interior toits exterior yarn supportin surfaces, orwvice versa, or each yard pacage may be first wound upon a tube or other suitable temporary holderand then transferred to such a pervious holder. Pervious holders ofdifferent kinds may be used, it being desirable to employ a holder whichoffers openings of suflicient aggregate area to the interior of the yarnpackage to permit free flow of the dyeing liquor or other treating fluidfrom the interior of the holder into the package, or vice versa, and theinvention enables pervious holders to be used which are incompressibleaxially and present peripheral yarn supporting surfaces of relativelysmall area, and are without obstruction or indentation from end to endof the holder, so that the yarn package is capable of movementlongitudinally on the holder. The pervious holder shown in the presentinstance is of a type shown and described in my prior application SerialNo. 80,316, filed January 9, 1926, which reference is made for acomplete illustration and description of its construction. For thepresent purposes, it is believed suflicient to describe this holder ascomprising a number of circumferentially spacedlongitudinally extendingyarn-supporting members 2 which form flutes between them and areparallel so that the holder will be of equal diameter from end to endand no obstructions exist which would interfere with the longitudinalmovement of the yard package with respect to the holder, the latterbeing axially hollow as indicated at 2 for the flow of the dye liquoraxially therethrough. The yarn-supporting members are suitably spaced topermit the radial passage of the dye liquor or other treating fluidthrough slots 2 formed between them, and the ends of the supportingmembers are united by inner and outer bands 3 and 4, these bands beingpreferably of reduced diameter with. respect to that of the portion ofthe holder formed by the supporting members. The yarn may either bewound initially upon such a holder, or it may be wound first upon apaper tube or other temporary form of holder which is of greaterdiameter than the pervious holder, and then wise displacement of theyarn package while the holders are placed end to end.

Each yarn package, according to the present invention, is compressedaxially while a suitable number of the packages are arranged endwise ina-series. As shown, it is preferable to employ for this purpose a pairof top and bottom or end compression heads 5 and a suitable number ofintermediate compression heads 5a. These compression heads arepreferably of conical form and of a diameter approximately equal to thatof the yarn packages with which they are to cooperate. The end heads 5are formed with tubular hubs 6 and the intermediate compression headsare formed also with tubular hubs So although the hubs 6a are common toa pair of the intermediate compression heads and serve to connect them.It will be understood of the compression heads are sufliciently large toaccommodate or fit loosely over the ends of the pervious holders, andthe compression heads are preferably so proportioned that when a seriesof yarn packages containing the pervious holders are assembled, the endsof the pervious holders will abut against one another while thecompression heads bear against the ends of the yarn packages and mayoperate to apply axial compression thereon. v

The series of yarn packages containing the pervious holders may beassembled in endwise relation with the end and intermediate compressionheads applied substantially as shown in Figure 1, and compression isapplied to and maintained upon the yarn pa'ckages by endwise compressionexerted upon the end compression heads 5. Different means may beemployed for applying this compression, a pair of plates 7 being shownfor this purpose in the present instance, each plate fitting over thetubular hub 6 of the respective end compression head and bearing againstthe latter, and a suitable number of threaded or other tensioning rods 8connect the plates, the plates being drawn together or toward oneanother by suitable manipulation of the nuts 9 on the tensioning rods,and after the requisite amount of compression has been applied, theplates and their tensioning rods will maintain such compression.

Compression exerted upon the end compression heads will be transmitteduniformly to all of the yarn packages in the series. Whilethe end heads5 will act directly upon the end packages to compress them, thesepackages may move axially on theirholders toward the intermediatepackages, thus transferring the compression from the end packages to theintermediate compression compression to the respective intermediatepackages. It will be understood that this uniform distribution of theaxial compressing force will take place throughout the series ofpackages irrespective of the number of packages comprising the series,the equalizing of the compression among all of the packages beingpermitted to take place by the ability of the packages to shiftlongitudinally on their respective holders and thus accommodatethemselves to the compression forces acting thereon, and hence equalizethe compression acting in opposite directions upon each package. Theaccommodating of the compression heads to the compression forces actingon each package is not interfered with by the holders as the tubularhubs of the compression heads fit loosely over the ends of the holdersand may, if necessary, pass more or less onto the holders.

It may be found desirable in some cases to employ means for limiting thecompression imposed upon one or more of the ackages. Such a limitingdevice is shown in ig. 4 to 6, it comprising for example, a tube 10 oneor more of which may be placed on each-of the rods 8 so that they areshiftable longitudinally and also rotatable thereon, each tube havingsuitably spaced lugs 11 projecting from a side thereof near its upperand lower ends. When it is desired to limit the compression imposed onany one or more of the packages in the assembly, the tubes 10 areshifted along the rods 8 to bring them opposite to the package orpackages whose compression is or are to be limited, and the tubes arerotated to bring the lugs 11 'thereon into position between the heads 5acontainin such package or packages between them. en the packages arecompressed, these lugs on the hmiting devices will limit the relativemovement of these heads toward one another and thereby limit the degreeof compression imposed ,onsuchpackage or packages.

The assembled packages'compressed as described may be placed in anysuitable dyeing or'other apparatus to efiect the dyelng or treatment ofthe yarn. For example, they may be placed in a dyeing apparatus of thesame general type as that shown in the prior patent of myself and F. H.Daniel, No. 1,052,817, granted February 11, 1913. In lacing theassembled and compressed pac ages in a machine of that type, the packageassemblies, such as shown n Fig ure 1, are placed in uprlght. poslt onbetween the top and bottom plates of the kier or treating chamber andthetubular hubs 6 of the top and bottom compres sion heads, or either oneof them may form a fluid-tightfit with one or the other of these platesso that treating fluid may be forced into the packages through one orthe other or both of the hubs of the end compresuniform pressure of thelatter while acting on the different yarn packages of the series; or thedirection of flow of the treating fluid may be reversed so that it willpass from the outside of the yarn packages inwardly to the centersthereof and the treating fluid may then be withdrawn through one or bothof the tubular hubs of the end compression heads. By producing anequalized axial compression upon each of the yarn packages of theseries, in the manner hereinbefore described, the yarn in all of thepackages will be of substantially the same density, and, moreover, thedensity of the yarn in each package will be substantially uniform, inconsequence, uniform permeability of the yarn in all of the packages isobtained by compressing the packages in the manner bled with respect tothe compression heads,

the previous holders may then be removed by endwise displacement fromthe packages and the latter will then be ready for further disposition.

The present invention enables uniform distributiorrof axial compressionto be produced and, maintaind ,in a series or plurality of yarn packagessothat uniform permeability ofthe yarn in all of the packages of theseries will be attained, and, moreover, the provision of theintermediate compression heads enables fluid-tightjoints to be obtainedeflectively between the ends of the different packages of the series,underthe compression applied to the end compression heads, thus avoidingleakage which has been likely to occur where it has been attempted toform such joints by direct contact between the ends of adjacentpackages. While the invention enables the results hereinbefore describedto be attained with yarn packages while they are mounted on perviousholders which are non-compressible axially and possess many practicaladvantages over axially ers and when so used, the results hereinbeforereferred to will be attained.

I claim as my invention l.
